将一种新型的复合式围护结构———水泥土复合式围护结构的位移分解为刚性位移和弹性挠曲，讨论了两种位移以及内力的分析计算方法，并以一个工程实例为基础讨论了水泥土复合式围护结构的各种工作性状，指出各设计要素的选择需要优化，各设计要素之间还要满足协调性的要求。 Displacement of a new type of composite envelope structure, ie, cement-soil composite envelope structure, is decomposed into rigid displacement and elastic deflection. Two displacements and internal force analysis and calculation methods are discussed and based on an engineering example. The various properties of the cement-soil composite envelope structure were discussed. It was pointed out that the selection of various design elements needed to be optimized, and the coordination between the design elements was also required.
